IMPROVEMENI IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 131,972, dated October8, 1872.

To all whom it may concern:

Be it known that I, TEEoDoEE F. RosE, of Barnegat, in the countyofOcean, in the State of New Jersey, have invented an Improved Fasteningfor WindoW-Sashes; and do hereby declare that the following description,taken in connection with the accompanying plate of drawing hereinafterreferred to, forms a full specification of the same, wherein I have setforth the nature of my said invention, by which the same maybedistinguished from others of a similar class, together with such partsas I claim and desire to secure by Letters Patent.

My invention relates to that class of locks or latches which are madeuse of for fastening sashes or holding the saine in any desirableposition; and the nature thereof consists in certain modifications inthe details of the construction of the same, hereinafter described andshown.

In the accompanying plate of drawing, which illustrates my invention andforms a part of the specification thereof, Figure lis an elevation ofthe fastener, with one ofthe side plates thereof removed, in order tomore fully exhibit the interior mechanism.; Fig. 2 illustrates thespiral spring by which the cam-wheel is operated; and Fig. 3 designatesthe rod by means of which the fastener is operated.

The construction, operation, and arrangement of the various parts of myinvention are as follows: i

In the drawing,- the letter A designates the casing, within which arearranged the camwhe'el or eccentric B, bolt C, and springs D and E. Thesaid casing may be placed in a Window-easement, either near the top ofthe lower sash or bottom of the upper one, as the case may be, so thattheeccentric fastener B may project a triie beyond the edge of the same.In either case the bolt C is above the camwheel B. The axle of theveccentric B :tits in a circular aperture cut through the post F, aboutwhich is arranged the spiral spring E, and is provided with a lugiitting into the hooked end of the said spring. A threaded slot, H, iscut in the axle of the eccentric for the reception of the rod I, whichpasses through a circular aperture in the casing, and is provided wit-ha knob, K, by which it may be operated. By turning the said knob thestud L upon the eccentric is made to engage with the lug M of the bolt Oand spring the same back' from the mortise in the Window-sash, unlockthe window, and allow it to be freely raised.

The window is held in any desired position after being raised by meansof the eccentric fastener B, which may be disengaged with facility bymerely turning theknob K.

Having thus described the construction and operation of my invention, Iwill indicate in the following clause what I claim, and desire to secureby Letters Patentthat is to say:

I claimy The serrated eccentric B, operated by the adjustable rod I, andhaving a stud, L, the spiral spring E, the bolt C, and the spring D, allcombined and operating together, as and for the purposes described.

In witness whereof I have hereunto subscribed my name this 8th day ofMarch, 1872.
